摘要: Testes from rats flown on Cosmos 1887 were compared with vivarium control and synchronous samples. The mean weights of flight testes, normalized for weight per 100 g, 6.4% less when the controls. Counts spermatogonia tissue sections (seminiferous tubules in maturation stage 6) five animals each group revealed 4% fewer testes controls 11% samples
